Application filed May 21, 1913. Serial No. 768,914.

To all whom it may concern:

Be it known that I, Nuns ANDRE NrunsnN, subject of the King of Great Britain, residing at Marton, New Zealand, have in vented a new and useful Improvement in Means forlnfiating the Pneumatic Tires of Motor-Carsand other Vehicles and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention has been designed in order to provide means whereby an ordinary inflation pump may be connected to and actuated by one of the driving wheels of a stationary motor car or other vehicle in order that thepneumatic tires of, the other wheels may be inflated withtho expenditure of a minimum of time and trouble. v v

The invention relates to improvements in the apparatus employed in that known class of inflating means, in which a pump has, its cylinder suspended on a pivot point on the vehicle frame and its plunger rodattached to a crank pin upon the vehicle wheel so that the rotation of the wheel will impart reciprocation to the pump plunger; The pumping operation. thus performed may then be utilized to inflate the tires of the other wheels of thevehicle than that to which the pump isattached. I

The invention consists in a special form of clamp for attaching the crank pin to the wheel and also in a special form of pivot pin upon which the pump cylinder may be mounted in the vehicle frame.

In the accompanying drawings suitable means for carrying out the invention have been illustrated, although others of similar principle in construction and operation may be employed without departing from the spirit of the invention.

In such drawings :Figure 1 is a side elevation of the rear portion of a motor car with the appliances fixed ready for working. Fig. 2 is a plan. Fig. 3 an end elevation, and Fig. 4 a front elevation of a suitable form of crank pin and clamp for its attachment to a wheel, the last figure showing it upon the spokes of the wheel. Fig. 5 is a plan, and Fig. 6 a front elevation of aclip for attachment to the pump cylinder and for pivoting such cylinder upon the car footbaard. r

a represents the pump which may be of any of the ordinary forms having the plunger actuating plunger rods and handle I) and which in this invention have attached to them a sleeve or like bearing 0 extending transversely across the handle.

(Z is the crank pin which is made of a di amcter such that the sleeve bearing 0 willfit neatly thereon. The pin is screwed into the back plate a of a pair of clamping plates 6 and f the front plate of which fits loosely on the pin. These plates are adapted to lie respectively behind and in front of the spokes g of the wheel and to extend across two of them, as shown in Figs. 1 and 2. A hand nut 71. is screwed on to the pin so as to engage with the outside face of the plate and thereby when screwed in to tighten the plates on to the wheel spokes and thus fasten the crank pin thereto. The clamp may be attached at any distance desired from the center of the wheel. The clamping plates shown in the drawings are made with their adjacent faces beveled to permit of their attachment to a wire spoke wheel in such a manner that the crank pin (Z will extend horizontally from the wheel. These faces may however be inade flat when the clamps are to be used for a wheel having wooden spokes, or the same plates may be used for either form of wheel by reversing their faces upon the pin. v

y (Figs. 5 and 6) is a clip into which the bottom end or foot plate 7.3 of the pump fits and in which it is ammed and held by means of the set screws m. The clip is attached to or formed in one with a spindle 77. extending at right angles therefrom. This spindle is adapted to fit into the bearings 0 fixed to the undersideof the footboard p of the car so that" it will be supported therein in such a manner as to be free to rock reciprocally. The pump end therefor inserted in the clip will be also supported.

It will be seen that when the crank pin (l has been fixed to the wheel and the pump inserted in the clip the pump may be suspended by passing the spindle a into the bearings 0 and by passing the sleeve bearing 0 over the crank )in as shown in Fig. 1'. lVhen therefore 1 1c wheell is rotated the pump plunger will be worked in and out, the pump oscillating with its clip inthe hcarin 0 so as to correspond with the vary ing angles with such bearings, assumed by the crank pin in its rotation with the wheel.

The appliances used may be readily carried in the tool box of the car and may be wheel from the ground a suflicient distance to enable it to rotate freely. The other three wheels of the car may then have their tires inflated, the pump tube 1' being made sufli ciently long to reach them. The appliances are then removed from this wheel and placed upon the driving wheel on the other side of the car and the first wheel in turn have its tire inflated.

If required a split pin 8 may be passe through the outer end of the crank pin d in order to prevent any liability of the plunger handle coming ofi' the pin while working. The length of the crank pin projecting outward from the wheel may be varied by screwing the pin in or out of the clamp plate 6 so that it may be used on cars having varying widths of mud guards.

In some cases, the pump cylinder may be attached to the crank pin on the Wheel and .the plunger attached to the car body without departing from the principle involved in the working of the invention.

What do claim as my invention, and desire to secure by Letters Patent is 1. Means for inflating the pneumatic tires plates together, an air pump having a plunger rod, a sleeve-bearing attached to said driving wheels, a nut for clamping said rod and fitting upon a crank pin, and means for pivotally suspending said air pump from the vehicle body 2. Means for inflating the pneumatic tiresof motor vehicles, comprising a crank pin threaded at its inner end, a pair-of clamping plates mounted on said pin and adaptedto be clamped to the spokes of one of the drlving wheels, a nut for clamp1 ng sald plates together, an air pump having a plunger rod, a sleeve attached thereto and fitting upon said crank pin, a cl1p adapted to receive the end of said air pump, and a spindle extending transversely from said clip, and bearings on the vehicle body for said spindle.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
